Description

COMPOSITION FOR SURFACE TREATMENT AND PROCESS

FIELD OF THE INVENTION

[0001] The disclosures herein relate to a composition comprising a synergistic combination of chemicals and to a process for using the same composition. More particularly, the process uses the composition in cleaning floors and surfaces previously provided with a coating commonly referred to as a wax coating. The combination of chemicals in the composition can be selected from microemulsion concentrates based on benzyl alcohol and tripropylene glycol monomethylether in combination with ammonium hydroxide (aqueous ammonia solution).

BACKGROUND OF THE INVENTION

[0002] The cleaning industry has used aqueous ammonia solution (a.k.a. ammonium hydroxide) in household cleaning for a number of years. One disadvantage of using aqueous ammonia solution is the amount of product required (5% - 30% ammonia) and the repulsive ammonia odor associated with the same. As a result, the use of aqueous ammonia solution as a cleaning agent in a substantially closed environment is not practical.

[0003] United States Patent No. 4,230,605 discloses a use of a polymeric material, a surfactant, ethylene glycol monobutyl ether and aqueous ammonia as a preferred cleaning composition for no-wax vinyl floors.

[0004] The disclosures of United States Patent No. 6,277,800 B 1 describe preparation and use of a household cleaning solution based on water, rubbing alcohol and liquid ammonia, in combination with a lemon scented liquid dish detergent.

[0005] United States Patent No. 6,403,546 discloses a composition for cleaning and enhancing the gloss of floors using a plasticizer, tributoxyethyl phosphate.

[0006] In addition to the above, cleaning compositions for floors and surfaces also use various types of surfactants and solvents, some with a negative environmental impact. For example, high H products / solutions (i.e., pH 12-13), and environmentally unfriendly solvents, such as phosphates with high solids content (e.g., 15% w/w), can be used.

SUMMARY OF THE INVENTION

[0007] The problem with ammonium hydroxide solutions is the environmental impact of the various solvents and surfactants used to keep the ammonia in solution. Further, the higher the concentration of ammonia, the more solvent and/or surfactants that are required. In addition to the environmental impact, aqueous ammonia also releases a noxious odor, which makes it difficult to use in closed environments.

[0008] What is needed are more environmentally friendly solvents and solvent combinations, including combinations that are free of the environmentally unfriendly butyl cellusolve used in floor wax stripping. Further, it would be desirable if the solvents and solvent combinations performed equally to known ammonium hydroxide

compositions and have low levels of solids in the composition.

[0009] Disclosed herein are composition made from a microemulsion and at least one additional component, including ammonium hydroxide, primary amines, secondary amines, and amino-ethanol. Some of the composition can also have an odor masking agent. Surprisingly, it was found that certain composition performed equally well to known cleaning compositions, while containing less ammonium hydroxide and lower solvent amounts.

[0010] In one aspect, an aqueous composition comprising a microemulsion is disclosed; wherein the microemulsion is provided to the composition in an amount of about 1.0% by weight to about 10% by weight, and further comprising one or more components selected from the group consisting of: aqueous ammonia solution (for example, 28-30% by weight, ACS grade), primary amines, secondary amines and amino-ethanol; in an amount of about 0.1 % by weight to about 5% by weight, and optionally further comprising an odor masking agent in an amount of about 0.01% by weight to about 3%» by weight. The microemulsion can include IN VIST A FlexiSolv™ 1150C microemulsion concentrate available from INVISTA or a microemulsion of benzyl alcohol and tripropylene glycol monomethylether.

[0011] In another aspect, an aqueous composition comprising a microemulsion comprising benzyl alcohol and tripropylene glycol monomethyl ether is disclosed;

wherein the microemulsion is provided to the composition in an amount of about 1.0% by weight to about 10% by weight, and further comprising aqueous ammonia solution (28- 30% by weight, ACS grade), in an amount of about 0.1% by weight to about 5% by weight, and optionally further comprising an odor masking agent in an amount of about 0.01% by weight to about 3% by weight.

[0012] In a further aspect, the microemulsion is comprised of benzyl alcohol, a nonionic surfactant, an amine component and water. The microemulsion may contain about 33% by weight of benzyl alcohol, about 12% by weight of a nonionic surfactant, about 22% by weight of an amine component and the balance is water. A first additional example can include microemulsions containing from 23 to 43% by weight of benzyl alcohol, about 2 to 22% by weight of a nonionic surfactant, and from 12 to 32% by weight of an amine component, with the balance being water. A second additional example can include microemulsions containing from 28 to 38% by weight of benzyl alcohol, about 7 to 17% by weight of a nonionic surfactant, and from 17 to 27% by weight of an amine component, with the balance being water. A third additional example can include microemulsions containing 30 to 36% by weight of benzyl alcohol, 9 to 15% by weight of a nonionic surfactant, and 19 to 25% by weight of an amine component, with the balance being water.

[0013] The nonionic surfactant may be selected from a group comprising allcyl sulfates, alkyl ether sulfates, alkyl ethoxylates, alkali metal salts of sulfo succinates, toluene sulfonates, xylene sulfonates and benzene sulfonates. The amine component may be selected from a group comprising long chained amines, di-amine, cyclic amines, branched di-amines, polyamino substituted alkanes, and C2-C5 alcohol amines. In one embodiment, the amine is a monoalkylamine, for example a monoisoalkyl amine, for example, monoisopropanolamine. [0014] In a further aspect, a process is disclosed for using the aqueous composition to remove wax from surfaces, particularly floor surfaces. The process comprises applying the aqueous composition to the floor or surface and allowing sufficient time for the composition to loosen the wax from the floor or surface. Examples of suitable times for loosen the wax from the floor or suface depend on several factors, including temperature, surface roughness, the amount and composition of wax applied to the floor, and may range from as little as a few seconds to as much as several hours, for example 5 seconds to 20 minutes, 30 seconds to 5 minutes, and 1 to 3 minutes. In one example, the contact time is 12 seconds.

DETAILED DESCRIPTION

[0015] An environmentally friendly aqueous composition is disclosed, which is based upon microemulsions and small quantities of aqueous ammonia to perform comparably to the market products without the negatives of selecting undesirable chemical raw materials or undesirable work conditions (likes fumes, odor). Adding a small amount of ammonia solution, or amines, as an "accelerator" or "adjuvant" improves the

performance of the composition in a process of stripping wax from surfaces. The composition can also include an odor masking agent.

[0016] One microemulsion that can be used in the disclosed aqueous composition is FlexiSolv™ 1150C from INVISTA.

[0017] The disclosed microemulsions are characterized by density (at ~ 22°C) of between 1.0 and 1.1 g/mL, for example 1.01 to 1.07 g/mL, for example 1.02 to 1.05 g/mL, for example 1.035 to 1.045 g/mL.

[0018] The disclosed microemulsions are characterized by viscosity (at ~ 22°C) of between 12 and 40 cSt, for example 15 to 38 cSt, for example 17 to 25 cSt.

[0019] The disclosed microemulsions are characterized by refractive index values of 1.4 to 1.6 (dimensionless), for example 1.43 to 1.51, for example 1.48 to 1.50. [0020] The disclosed microemulsions are characterized by pH values (when diluted to 10 weight percent in water) of between 4 and 8, for example 4.2 to 7, for example 4.5 to 6.8.

[0021] The disclosed microemulsions are characterized by freezing point below 25°C, for example below 20°C, for example below 0°C, for example below 10°C and below 12°C.

[0022] Initial boiling point for the disclosed microemulsion is generally below 220°C, for example.

[0023] These emulsions are targeted to household cleaners and with an emphasis on ecologically friendly materials, also called "eco-friendly" solvents. The emulsions can include INVISTA FlexiSolv™ microemulsions, including FlexiSolv™ 1150C, which are clear, single phase solutions that offer strong solvency power in a water-dilutable, water- rinseable system. The FlexiSolv™ microemulsions, when combined with ammonium hydroxide for wax stripping, do not have the negative side-effects of noxious vapors associated with ammonia household cleaners. Further, the FlexiSolv™ microemulsion compositions do not contain environmentally unfriendly chemicals (e.g., butyl cellusolve) and also provide low solids content.

[0024] The concentration of microemulsion, including INVISTA FlexiSolv™ in the aqueous composition can range from about 1.0% by weight to about 10% by weight, including between about 2 to about 7% by weight, and between about 3 to about 5% by weight. The concentration of ammonium hydroxide can range from about 0.1% to about 5% by weight, including between about 0.5% to about 3% by weight, and between about 0.8% to about 1.8% by weight.

[0025] The ammonium hydroxide can be any suitable grade, for example ACS grade, electronic grade or industrial grade, provided that the ammonium hydroxide does not contain impurities that would be detrimental to the efficacy or stability of the resulting microemulsion.

[0026] Also disclosed is a process for stripping wax from floors and surfaces using an aqueous composition comprising a microemulsion and aqueous ammonium hydroxide. The process comprises applying the aqueous composition to the floor or surface and allowing sufficient time as described above for the composition to loosen the wax from the floor or surface. A portion of the loosened wax is entrained in the aqueous composition, so that it may be removed by rinsing the floor or surface. The other portion of the loosened wax is still bonded to the floor or surface, however, the bond strength after application of the aqueous composition is lower than the bond strength before application. This wax may be removed by subsequent applications of the disclosed aqueous composition, or by other mechanical methods such as scrapping, scouring, or scrubbing the floor or surface.

[0027] The microemulsion in the disclosed process can include TNVISTA

FlexiSolv™ 1150C microemulsion concentrate in a concentration from about 1.0 to about 10% by weight, including between about 2 to about 7% by weight; and between about 3 to about 5% by weight. The aqueous ammonium hydroxide is present in a concentration from about 28% to about 30% by weight solution, ACS grade. This results in an ammonium hydroxide concentration in the composition in a range of about 0.1 to about 5% by weight; including between about 0.5 to about 3% by weight; and between about 0.8 to about 1.8% by weight.

[0028] Another microemulsion that can be used in the disclosed aqueous

compositions and processes is a combination of benzyl alcohol and tripropylene glycol monomethylether. The tripropylene glycol monomethylether is present in a

concentration from about 1.0 to about 10% by weight, including about 2 to about 7% by weight, and between about 3 to about 5% by weight.

[0029] The disclosed aqueous compositions and processes can also include a substitute for ammonium hydroxide. This substitute can include a compound with a primary amine and/or a secondary amine, and/or an amino ethanol, present in the composition in a concentration range of about 0.1 to about 5% by weight; including between about 0.5 to about 3% by weight; and between about 0.8 to about 1.8% by weight. Examples of suitable primary amines include include methylamine, ethylamine and propylamine. Examples of suitable primary amine alcohols include ethanolamine and propanolamine. Examples of suitable secondary amines include include include dimethylamine. Suitable suitable secondary alcohol amines include methylethanolamine.

[0030] One optional component of the composition is an odor masking agent, including d-limonene (l-methyl-4-(l-methylethenyl)-cyclohexene; CAS number 5989- 27-5) or a similar florid-smelling odor masking agent (Examples?). The masking agent is present in an amount of between about 0.01 to about 3% by weight. Other optional additives may be included in the composition such as the chelants EDTA, HEDP or MGDA, a thickening agent (e.g., carageenan alone or with sodium stearoyl lactylate); colorants such as dyes and pigments and other fragrances.

[0063] "Microemulsion", as used herein, is a specific type of emulsion where the size of the dispersed phase droplets (typically < 100 nm in diameter) is small compared to the wavelength of light, making the microemulsion appear clear and transparent to the eye when observed under diffuse, multidirectional light. Tyndall effect light scattering can generally be observed when a sample is illuminated by a collimated beam of light and an observer views the sample from an angle relative to the path of the light beam, such as an angle of from about 20 degrees to about 160 degrees, for example an angle of from about 45 degrees to about 135 degrees, for example an angle of about 90 degrees. Usually gentle mixing is sufficient to form a microemulsion. Microemulsions are thermodynamically stable and do not spontaneously separate.

[0064] "Microemulsion concentrate", as used herein, is a composition comprising one liquid phase and a surfactant package that, when combined with a second liquid phase immiscible with the first liquid phase, forms a microemulsion.

[0065] "Substituent" as used herein means a branch from a parent structure.

TEST METHODS

[0066] BYK- Gardner Instrument USA (9104 Guilford Road, Columbia, MD 21046- 2729 United States; BYK- Gardner GmbH, Lausitzer StraBe 882538 Geretsried, Germany) is used to check performance of wax cleaning from "soiled" tiles. Details of the test method are explained in the example.

[0067] Color is measured using the HunterLab Ultrascan Pro, or equivalent, color measurement spectrophotometer from Hunter Associates Laboratory Inc., Reston, Virginia, USA. Color is rated on the color scale Hunter L,a,b. As one skilled in the art of color measurement would know, the L,a,b scales simulates color as:

L (lightness or luminance) axis - 0 is black, 100 is white

a (red-green) axis - positive values are red; negative values are green and 0 is neutral b (yellow-blue) axis - positive values are yellow; negative values are blue and 0 is neutral.

[0068] All colors visually perceivable are measurable in L,a,b scale. The scale can also measure the color difference between a sample and a standard.

EXAMPLES

[0069] The following examples are provided to illustrate the various aspects of the disclosed compositions and processes. It should be noted that ratios, concentrations, amounts, and other numerical data may be expressed herein in a range format. It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a concentration range of "about 0.1% to about 5%" should be interpreted to include not only the explicitly recited concentration of about 0.1 wt % to about 5 wt %, but also the individual concentrations (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.5%, 1.1%, 2.2%, 3.3%, and 4.4%) within the indicated range. The term "about" can include ±1%, ±2%, ±3%, ±4%, ±5%, ±8%, or ±10%, of the numerical value(s) being modified. In addition, the phrase "about 'x' to 'y'" includes "about 'x' to about 'y"\

Example 1.

[0070] In an example the following test method is employed.

[0071] Preparation of tiles for soiling: eight (8) vinyl 4" tiles are cleaned with a glass cleaner, rinsed and dried in 40°C oven with nitrogen (N2) purge for 2 hours.

After cooling to room temperature the color coordinate "L" of the wax-free tiles is measured and recorded as LI and the tiles are ready to be soiled with "dirty wax".

[0072] Preparing Wax Stains: 500g Red Max Pro Low Maintenance Floor Finish Item # 216595 (a wax dispersion commercially available from Enforcer Products, a division of Acuity Products Inc., PO Box 1060, Cartersville, GA 30120, USA) is prepared with 1.0g lampblack dispersed in the wax dispersion and homogenized for one (1) minute to form a dispersion. This wax-lampblack dispersion is subsequently rolled on the tile with a paint roller. Four (4) coats are applied and measured visually. (Whizz roller #94062) 15 minutes between coats to dry. The soiled tiles are air dried for 30 minutes; then dried in 40°C oven for 18 hours. Once the soiled tiles are cooled, the color coordinate "L" is measured and recorded as L2. These "dirty tiles" are ready for cleaning. [0073] Cleaning Test: Soiled tiles are cleaned on a BY Gardner Abrasion tester set (number of cycles can vary, but typically up to 30 cycles). A cleaning sponge is placed in hard water (hardness?) and excess water squeezed out. Tiles are soaked in cleaner (lying flat in a pan, face up) for two minutes and then supported vertically to drain for 15 seconds.

[0074] Tile is placed in the tile in BYK Abrasion tester run full 30 cycles. The number of cycles to clean and visual percent (%) clean is recorded.

[0075] Performance Evaluation: After running the desired number of cycles for cleaning, the tiles are rinsed in tap water 3 times (dipping) and supported at an angle to dry. After drying, color coordinate "L" measurements of the cleaned tiles are taken and recorded as L3. The cleaning effectiveness, or percent cleaned, is calculated according to the formula (L3 - L2) / (LI - L2) x 100% where LI, L2, and L3 are as defined above.
